Need help with simple code

I'm really new to coding and I made this very small piece of code:

term.clear()
term.setCursorPos(1,1)
if rs.getBundledInput("right", colors.green) then
mon.write("1")
end

but when I run it it tells me I there's a nil value on line 4.

EDIT: omg sorry, just found my mistake, sorry Im really new.

No Problem :P/>/>
